Boost Your Miata Performance with the Racing Beat Miata Header – Plus Power Tuning with JB4 in Canada



When it comes to upgrading your Mazda Miata, performance enthusiasts know that every detail under the hood counts. Whether you’re cruising through twisty backroads or tracking your NA/NB/NB2 Miata for pure driving joy, upgrading the exhaust header is one of the best ways to unlock real horsepower. That’s where the Racing Beat Miata Header shines.

At My Parts Guy, we’re passionate about giving drivers across Canada access to premium performance parts—including hard-to-find headers and intelligent tuning modules like the JB4. If you’re looking to elevate your Miata’s exhaust flow and tune your turbocharged ride, we’ve got you covered.

Why Upgrade to a Racing Beat Miata Header?

The stock exhaust manifold on older Miata models (especially the NA and early NB generations) is restrictive. It's designed more for emissions and cost efficiency than for airflow. A performance header like the Racing Beat Miata Header is engineered for optimized exhaust scavenging, helping your engine breathe better and produce more power—especially in the mid-to-high RPM range.

Here’s why it’s a game-changer:

  • Mandrel-bent tubing for smooth airflow

  • Thicker flanges for better durability and no leaks

  • High-quality welds and perfect fitment

  • Dyno-proven gains in horsepower and torque

  • Designed specifically for naturally aspirated Miatas

When you install a Racing Beat header, you’ll feel the difference immediately. The throttle response improves, the engine note deepens, and your car simply pulls harder—without sacrificing reliability.

A Perfect Mod for NA & NB Miata Owners

Whether you have a 1990 NA6, a 1.8L NB1, or a later NB2 Miata, the Racing Beat Miata Header is a popular choice among DIY tuners and weekend racers alike. It bolts on easily and pairs well with a high-flow catalytic converter and cat-back exhaust system.

For those chasing power with a factory-like feel, Racing Beat strikes that balance beautifully. It’s also CARB certified in many U.S. states, making it a worry-free upgrade for emissions-conscious enthusiasts.

Power Tuning in Canada? Enter JB4

Now, let’s shift gears. What if you drive a turbocharged car—BMW, VW, Kia, or even a Supra—and you want more power without complicated installs? This is where the JB4 tuning module comes in.

JB4 Canada is exploding in popularity, and for good reason. It’s one of the easiest, safest, and most cost-effective ways to tune your turbocharged engine without needing a laptop or dyno tuning session. With a JB4, you can:

  • Increase horsepower and torque

  • Adjust boost levels and timing

  • Read and clear diagnostic codes

  • View real-time engine data

  • Use your smartphone to control tuning maps

Best of all, it’s plug-and-play. Most installations take under 30 minutes and can be reversed just as easily—perfect for leased vehicles or cautious modders.

At My Parts Guy, we ship JB4 modules across Canada, helping enthusiasts get more out of their factory turbocharged engines safely and efficiently.
